Implement impacted tests detection #8188

nikita-tkachenko-datadog · 2025-01-13T11:29:10Z

What Does This Do

Implements Impacted Tests Detection CI Visibility feature (milestones 1.X as defined in the RFC linked below):

detects which test cases are "impacted" (for now a test is impacted if the body of the test method was changed in a PR)
marks impacted tests with test.is_modified:true tag
if Early Flakiness Detection feature is enabled, applies it to every impacted test
